Ir important peaks
WebHowever, you can use IR spectroscopy much more intelligently and learn the important peak positions much more easily if you understand a lit-tle more about the physical basis of IR spectroscopy. Two aspects of IR absorption peaks are particularly important. First is the position of the peak—the wavenumber or wavelength at which it occurs. WebThe absorption bands in IR spectra have different intensities that can usually be referred to as strong (s), medium (m), weak (w), broad and sharp. The intensity of an absorption band …

WebAug 28, 2024 · The Raman frequency shift is identical to the IR peak frequency for a given molecule or functional group. As mentioned above, this shift is independent of the excitation wavelength, giving versatility to the design and applicability of Raman instruments. The cause of the vibration is also mechanistically different between IR and Raman. http://www.chem.ucla.edu/~bacher/spectrocopy/IR1.html
